  1. 1. The Tjårrojåkka apatite-iron and Cu (-Au) deposits, northern Sweden products of one ore forming event

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Åsa Edfelt; Luleå tekniska universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related apatite-iron (Kiruna type) and Cu (-Au) deposits in Sweden. The results from this project show that the two deposits are genetically related and indicate the presence of a younger, previously unknown, 1780 Ma generation of apatite- iron ores in northern Sweden.

  3. 3. The Älgträsk intrusion-related Au (Cu, Zn) deposit, Skellefte district, northern Sweden : Relationships between ore forming events in the Palaeoproterozoic Jörn intrusive complex

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Therese Bejgarn; Luleå tekniska universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : Palaeoproterozoic intrusion hosted and intrusion related deposits such as the Älgträsk Au±Cu±Zn, Åkerberg Au, Älgliden Cu–Ni±Au, and the porphyry style Järvträsk Cu±Mo±Zn, Granberg Cu±Mo and Tallberg Cu–Au±Mo deposits are situated in the northern part of the Skellefte District, northern Sweden. These deposits are all hosted within the oldest unit of the Jörn intrusive complex (JIC). LÄS MER

  4. 4. Mineralogical, chemical and textural characterisation of the Malmberget iron ore deposit for a geometallurgical model

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Cecilia Lund; Luleå tekniska universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Sammanfattning : The northern Norrbotten ore province is an intensely mineralised area and has traditionally been a very important mining district. It contains Fe, Cu-Au, Au, and Ag deposits ranging from world-class ore deposits to small and uneconomic ones (Martinsson 2004). The most important are the Kiruna and Malmberget iron ores and the Aitik Cu-Au deposit. LÄS MER

  5. 5. Improving trace metal characterisation of ore deposits – a crucial step towards sustainable mining

    Detta är en avhandling från Luleå University of Technology

    Författare :Mathis Warlo; Luleå tekniska universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ore Geology; Malmgeologi;

    Sammanfattning : Sustainable mining, including the utilisation of an ore body to its full potential, is becoming increasingly important for human society as the demand for metals increases. In order to maximise the recovery of useful metals, detailed characterisation of the ore prior to processing is vital. LÄS MER
